4. Monitoring of Pesticide Residues in Surface and Subsurface Waters, Sediments, and Fish in Center-Pivot Irrigation Areas
In this study, the monitoring of pesticide residues, which show potential for environmental contamination, in center-pivot irrigated areas in the Brazilian cerrado, was performed. The pesticides monitored were acephate, atrazine, azoxystrobin, buprofezin, carbofuran, cyproconazole, chlorpyrifos, difenoconazole, diuron, imidacloprid, malathion, methamidophos,

5. Métodos para análises de HPA e BTEX em águas subterrâneas de postos de revenda de combustíveis: um estudo de caso em Campo Grande, MS, Brasil
Two methods using headspace solid-phase microextraction and gas chromatography - mass spectrometry were developed for the determination of polycyclic aromatic hydrocarbons (PAH) and BTEX. Best results were obtained using DVB/CAR/PDMS fiber, with 10 min extraction at 25 °C and 0.15 min desorption at 260 °C (BTEX), and PDMS/DVB fiber, with 60 min extraction

6. MONITORING THE FLUCTUATION OF THE WATER TABLE IN UNCONFINED AQUIFERS FOR EVALUATION OF THE POTENTIAL RECHARGE IN OUTCROP ZONE OF THE GUARANI AQUIFER SYSTEM IN CACEQUI - RS/BR / MONITORAMENTO DA FLUTUAÇÃO DOS NÍVEIS DE ÁGUA EM AQUÍFEROS FREÁTICOS PARA AVALIAÇÃO DO POTENCIAL DE RECARGA EM ÁREA DE AFLORAMENTO DO SISTEMA AQUÍFERO GUARANI EM CACEQUI - RS
This research aimed to estimate the recharge and groundwater water table fluctuation in areas with withdrawals of groundwater and surface water related to the variation of groundwater levels and rainfall events. The two areas of study was inserted within the Cacequi Municipality, which is located in the Rio Grande do Sul state, southwestern Brazil, in the Gu

7. FLUTUAÇÃO DOS NÍVEIS DE ÁGUA SUBTERRÂNEA EM MICROBACIAS HIDROGRÁFICAS DO RIO VACACAÍ-MIRIM / GROUNDWATER LEVELS FLUCTUATION IN VACACAÍ-MIRIM RIVER SMALL WATERSHEDS
The intention in this work is to study (locally) the fluctuation system of groundwater levels in two small watersheds. We selected Rancho do Amaral and Rincão do Soturno small watersheds for being representative of the first order streams which compose the Vacacaí-Mirim river watershed headwaters. Both are located at the border of Paraná Sedimentary Basin

8. Monitoramento de agrotóxicos em áreas irrigadas por pivô central na microbacia do Tijunqueiro, município de Morrinhos, Goiás / Pesticides monitoring in irrigated areas by central pivot in the Tijunqueiro Watershed municipality of Morrinhos, Goias
The importance of pesticides to the agricultural system production is indisputable, since they are part of the basics inputs, however, it is essential that they be used properly to be preserved not only the quality of the growing product, but also of their own natural resources, especially soil and water. In this study was conducted the pesticides monitoring

9. Oil-water liquid flow rate determined from measured pressure drop and water hold-up in horizontal pipes
Stimulated by rapid progress in down-hole measuring techniques production engineers wonder whether in the near-future monitoring of oil/water production rates for horizontal wells can become possible on the basis of measured oil/water pressure losses and water hold-ups. A complicating issue is that these measured data depend on the oil and water flow pattern
